The development of miniature devices has generated a large demand for dielectric polymers with high energy storage density,especially at high ***,poly(methyl methacrylate)(PMMA)-coated nanodiamond(ND)particles were incorporated into a polyimide(PI)substrate to fabricate ND-g-PMMA/PI(NPP)*** found for the first time that with a very low content(0.4 vol.%)of ND particles,NPP-0.4 composite material gave the dielectric constant of 4.4,which is 37.5%higher than that of the PI *** maximum energy density of the NPP-0.4 composite film achieves 9.4 J cm^(-3)at room temperature,which is 54%higher than that of the PI ***,we found that the NPP-0.2 composite reaches the highest energy density and discharge efficiency of 5.77 J cm^(-3)and 72.3%at 150℃,which are 104%and 51.3%higher than those of the PI film at 150℃.This result shows a much higher energy density than most previously published results for high-temperature polymer *** phenomenon can be explained by the simulation results using COMSOL in which the interface polarization of ND/PI composites reached their maximum value with ultralow ND contents(0.4 vol.%).This research shows great promise for polymer capacitors with relatively high energy density at high temperatures.

pH plays a vital role in various cellular activities, and real-time observation of the intracellular p H through a p H indicator is very important for studying many physiological processes. In this paper, we studied the p H response of Trp–Trp dipeptide and its derivatives(NATrp_2Me, NBTrp_2 and Trp_2Me) by steady-state and time-resolved fluorescence spectroscopy. Both the fluorescence intensities and lifetimes of Trp–Trp dipeptide as well as Trp2 Me were functions of p H in the physiological range from 5.5 to 9.0. However, NATrp_2 Me and NBTrp_2 showed no difference. The exposed amino was found to be pivotal for its p H dependence. Moreover, an artificially synthesized tetrapeptide(Trp–Trp–Ala–Ser) confirmed the p H sensitivity of N-terminal Trp–Trp residues. The p H values could be quantitatively determined from the fluorescence intensities and lifetimes of the N-terminal Trp–Trp residue. Thus, the N-terminal Trp–Trp residues may be fused into the polypeptides/proteins to serve as an intrinsic p H indicator in fluorescence spectroscopy and imaging.
